SPINNING- SPECIFICATION forming part of Letters 1? MACHINE.

atent No. 251,001, dated December 13, 1881.

Application filed June 9, 1881. (Model.)

T 0 all whom it may concern Be it known that l, PHILIP TOWNSON, of

Thompsonville, in the county of Hartford and State of Connecticut, haveinvented a new and useful Improvement in Spinning-Machines, of which thefollowing is a specification. Figure 1, Sheet 1, is an end elevation ofmy improvement. Fig. 2, Sheet 2, is a vertical section of the same. Fig.3, Sheet 3, is a plan view of the same. Fig. 4, Sheet 4, is a sideelevation of the same, partly in section. Fig. 5, Sheet 4, is asectional plan view of the mechanism for stopping the spindle, takenthrough the line as m, Fig. 4, and showing the position of thestop-lever when the spindle is in motion. Fig.6, Sheet 4, is the sameview as Fig. 5, but showing the stop-lever in position for stopping thespindle. Figs. 7 and 8 are detail views, showing the two-toothedratchet-wheel and the devices operating in connection therewith.

Similar letters of reference indicate corresponding parts.

The object of this invention is to automatically change the speed ofspindles when the bobbins are about two-thirds filled, and also tofacilitate the stopping of the spindles when the fliers have beenstopped.

In the accompanying drawings, A represents the frame of the machine.

B are the spindles, which revolve in hearings in the frame A and in theframes C, that raise and lower the said spindles B.

D are the fliers, which revolve at their lower ends upon the spindles Band at their upper ends in bearings connected with the frame A.

To the arms of each flier D is attached a ring, D, to serve as a guardto prevent the threads of adjacent bobbins from becoming entangled. Withthe lower end of each flier D is connected a whirl, E, around whichpasses a band, F. The band F also passes around a pulley, Gr, attachedto the main shaft H, to which the power is applied. Upon the spindle Bis placed a whirl, I, around which passes a band, J. The band J alsopasses around a pulley, K, attached to a second shaft, L, so that thespindles B and the fliers D will be revolved at a different speed bygiving a different speed to the two shafts H L.

To one end of the main shaft H are attached two small gear-wheels, M N,the teeth of which mesh respectively into the teeth of two largegear-wheels,OP. Theteethofthegear-wheels O P mesh respectively into theteeth of the small gear-wheels Q R, attached to the end of the shaft L.The small gear-wheels M N are made of the same size. The largegear-wheels O P are made of the same size; but the small gearwheels Q Rare made of different sizes, the gear-wheel Q being the larger. Thelarge gearwheels 0 P are pivoted to gudgeons S, attached adj ustably toa vibrating frame, T, by means of slotted plates U, or other suitablemeans, so that the gear-wheel O can be thrown into gear with thegear-wheels M Q, to give the spindles B a slower movement, or thegear-wheel P can be thrown into gear with the gear-wheels N R to givethespindles B a faster movement.

The frame T, at its lower end, is pivoted to and rides upon the shaft L,near its end. The upper part or arm of the frame T works in a keeper, V,attached to the frame A, or to a' support attached to the said frame.The upper end or arm of the frame T is forked to receive the cam W, bywhich the said frame T is movedto shift the gearing and change the speedof the spindles. The cam W is attached to the outer end of a shortshaft, X, which works in bearings in the frame A, or in a supportattached to the said frame A.

Upon the inner part of the shaft X is placed a loose gear-wheel,Y, whichis made to carry the said cam-shaft X with it in its revolution by aspring-pawl, Z, attached to the said gearwheel Y, and which engages witha ratchetwheel, a, formed upon or attached to the said cam-shaft X. Withthis construction the camshaft X can be turned forward faster than thegear-wheel Y without interfering with the regular movement of the saidgear-wheel Y. The teeth of the gear-wheel Y mesh into the teeth of anintermediate gear-wheel, b, pivoted to a support attached to/ the frameA. The teeth of the gear-wheel 12 mesh into the teeth of a smallgear-wheel, 0, attached to the inner end of a short shaft, (1, whichrevolves in bearings attached to the frame A, and to its outer end isattached a worm-wheel, e. The teeth of the worm-wheel e mesh into thethreads of a worm or endless screw, f, attached to the end of a shortshaft, 9, which revolves in a long hearing attached to the frame A.

To the upper end of the shaft g is attached a worm-wheel, h, the teethof which mesh into the threads of a worm or endless screw, 1', attachedto the end of the shaft j. The shaft j revolves in bearings attached tothe frame A, and to its other end is attached a pulley, 70, around whichpasses a band, I. The bandl also passes around a pulley, m, attached tothe main shaft H, so that the cam W will be driven from the said mainshaft. The gearing connecting the cam W with the main shaft H is soarranged as to turn the cam W through one revolution while the bobbinsare being filled.

To the shaft j is attached an eccentric, n, withwhich is connected theend of a connecting-bar, o. The other end of the connectingbar 0 ispivoted to the lower end of a lever, 19, whichis pivoted to the innerend of the camshaft X.

To the upper end of the leverp is pivoted a pawl, g, which engages withthe teeth of the two-toothed ratchet-wheel r, attached to the cam-shaftX, as shown in Figs. 7 and 8. The teeth of the ratchet-wheel r are soarranged that the pawl q will engage with them successively as the camWreleases each branch of the forked upper end of the frame T. Thus itwill be seen that, the Wheel Y being loose upon shaft X, the latter maybe turned more rapidly than said wheel by means of the mechanism at 0 pq r, of which the ratchet r is fast to said shaft, so that thegear-wheels O P will be shifted quickly, to prevent any interruption orirregularity in the movements of the machine.

Upon the spindle B is screwed, or to it is otherwise attached, the hubof the double disk or wheels, between the parts of which, near one side,is pivoted a lever, t. The inner part of the lever t is made heavy, oris weighted, and is curved, so that it can pass partially around the hubof the double wheel s. With this construction, when the spindle B is inmotion, the centrifugal force engendered by the revolution of thesaidspindle will throw the heavy inner part of the lever 23 outward, asshown in Fig. 5, drawing the outer part of the said lever inward towardthe rim of the double wheel 8.

When the operator wishes to stop a flier and spindle, he places theforefinger of his left hand upon the top bearing of the flier, thenbrings the palm of this hand into contact with the flier, and therebystops it. Then with a finger of the right hand he touches the doublewheel or disk attached to the spindle on its outer edge, thus placinghis finger in position to come in contact with the outer end of thelever, which is thus caused to immediately come out into position tocatch on the arm of the flier, thus stopping the spindle.

Having thus fully described my invention, Iclaim as new and desire tosecure by Letters Patent 1. The combination, with the vibrating frame T,the gear-wheels O P, the gear-wheels M Q N R, shafts H L X, and the camW, of the loose gear-wheel Y, spring-pawl Z, ratchet-wheel a, thegear-Wheels I) c, shaft 61, worm-wheel 0, endless screw f, shaft 9,worm-wheel h, endless screw 3, shaftj, band 1, and pulleys k m, as andfor the purpose specified.

2. The combination, with the vibrating shifting frame T, provided with aforked upper end, of the cam W and its driving mechanism, thetwo-toothed ratchet-wheel r, and the pawl q and its operating mechanism,substantially as herein shown and described, whereby the said cam ismoved quickly, as it vibrates the shifting frame in changing thegearing, to prevent the movements of the operating parts of the machinefrom being interrupted, as set forth.

3. The combination, with the spindle B and flier D, of the double wheelsand the weighted lever t, substantially as herein shown and described,whereby the spindle can be readily stopped, as set forth.
